• They are small in size and flexibility for heating and cooling individual rooms.
• Units can be zoned. Some models can have as many as four indoor air handling units, connected to one outdoor unit. Each zone has its own thermostat, so you only need to condition that space when it is occupied, saving energy and money.
• In some applications, mini-split systems are much easier to install than a traditional central HVAC system. The hook up between the outdoor and indoor units only require about three inch hole through a wall for the conduit. This makes this an ideal unit for conditioning a basement space.
• Since mini-split systems have no duct work, they avoid the energy loss associated with forced air systems.
• Compared with other “add-on” systems, mini splits offer more flexibility in interior design options. Indoor air handlers can be suspended from a ceiling, mounted flush into a drop ceiling, or hung on a wall.
• Mini-split systems offer higher security. These systems only require a small hole in the wall, where window mounted room units are an easy entrance for intruders.
• Trane includes their “Auto Clean” feature on all ductless indoor units. Providing triple filtration, reduces moisture and keeps the air you breath clean.
• More energy efficient since energy is no longer being lost in poorly insulated ductwork
